libmach: remove obsolete fishy case in mips header parsing
This code seems to be for the specific case of when
mips 3000 binaries were being run on a mips 4000 kernel.
As far as I know, our only current mips magic refers to the
5000 (at least), and the 4000 specific magic formats are mostly a relic.
There is currently no bootable system in which this code
path is correct. In any case, hardcoding /proc/1 is not the solution.
